iOS - How to detect a session timeout on UIWebView

Question

I have a UIWebView displaying a website that has a timeout policy (idle for 1800 seconds). Since I use a custom login view to connect to the site, I want to call this same custom view after the website has issued the timeout alert.

How can I detect that such an alert has been issued to the webview, so I can call my code from there?

Thank you for your help.

Answer 1

如果网站在超时时重定向到特定页面，则可以查看该页面是否已加载到UIWebViewDelegate的webView:shouldStartLoadWithRequest:navigationType:方法中。

从UIKit的角度不知道如何解决这个问题，但是如果知道会话超时，则可以在其中一个控制器中创建一个NSTimer，以在定义的经过时间提醒您，并在应用程序每次调用您的网站时将其重置。
